We liked the comfort and seats. The crew was not very friendly nor did they check on us to see if we needed anything. Had to ask for water several times

We liked the comfort and seats. The crew was not very friendly nor did they check on us to see if we needed anything. Had to ask for water several times

The rules regarding business class lounge hotel/room access were very confusing. Between flights we had an 11 hour layover in Istanbul, but were denied a room to rest as our layover was too long?? Keep in mind that we arrived there at 3:30am after a long flight. Even multiple Turkish airlines employees were inconsistent with the rules. We ended up paying a high price at the Yotel in the airport in order to get some rest. Good thing I did, as a medical emergency was declared on the flight from Istanbul to Atlanta and I was apparently the only physician on board. Luckily I was able to stabilize the passenger and the flight wasn't diverted. The crew called an overhead announcement for a medical doctor, but insisted that I show them a copy of my medical license which I did. Very strange in my 35 years as a physician and responding multiple times to inflight medical emergencies over the years. I was very glad the passengers issue was resolved, but an acknowledgement of at least a thank you from the crew would have been appreciated.

I wasn't able to bring my little dog with me, because of the feedback team's extremely slow response. How are they even allowed to operate with this paste??

The sleeper seats, the staff, and the food was truly delicious. I loved the mocktail options.

Great service. Seat was a bit small but it was fine. Food was great

Horrible service at the baggage claim. Stuck on plane for an hour due to taxing and no gate.

I really would like it if they provided at least some limited free wi-fi.

The crew was awesome. My husband fell while traveling to the WC and got a head abrasion. The crew helped him greatly and a physician that was also on the flight checked him out as well. They all get an A+!

Same as before boarding process and lack of crew experience in the process

Excellent service. Made United 's business class look like a cattle car

Was very bad the cancel the flight after when we arrived to London

They lost my baggage and still waiting an update when I can receive it

American Airlines is the worst airline to fly. you can’t get on an earlier flight if you don’t have ‘status’, they cancel their flights with no warning, and they lie about why their flights are delayed so they don’t have to pay for meals or hotels. They lost me as a customer after this trip. I’ll be flying Delta or Untied from now on.

The checkin process is always horrendous with this airline. They never have enough people working the desk or people assisting in the lines. Rude and unbothered. I never pick British Airways- I always get swapped in via American Airlines and may need to stop using American Airlines as well. No entertainment in flight. And they seem more concerned about selling food and drinks then they are about customer comfort

Late from Istanbul. Canceled my seat to NY in London although I've been on time for boarding. Didn't provide with hotel and shuttle, no food, just sleeping and hygiene bag. Hope, they will refund me.

Terrible service. Stewardess behavior horrible. No sense of customer service. Seats were small, in general very bad experience which is not the case for me on other international flights via BA

Great!!! The first flight was a little painful because the chair wasn’t reclining and my back was destroyed by the time I got in London. But the second flight was perfect!! Super comfortable, the food was amazing, the crew super polite and helpful. Overall, I had a good experience

TIRED OLD plane. Seat cushion is completely old and NOT cushion at all; after an hour of flying butt hurts. Boarding is a complete disaster. No one respects the boarding groups, and the BA boarding crew care less about boarding groups or Tier status. What is the point of spending all this money on Business Class tickets when no one respects the boarding system? It took 90 minutes since we landed to get our luggage. 20 minutes to show on the screen which belt we are supposed to go to and another 1 hour to get our luggage - not the kind of service you will expect from BA at LHR

My ticket was cancelled unannounced and I was left stranded in the air port

My luggage di dnot arrive till two days later and after several phone calls and unpleasant conversations
